Spatial anomaly

A spatial anomaly is a very broad term for any sort of extraordinary disruption in the space-time continuum. Often, they can take the form of irregularities in gravity, ripples in space that can damage equipment and personnel, alterations in the laws of physics, and areas of disruption inimical to the Humanbrain.

The spatial anomalies in Star Trek: Enterprise were essentially the answer that the show's writers came up with as to why parts of the Delphic Expanse didn't adhere to the usual laws of physics. "When you say that in the Expanse the laws of physics don't apply in certain areas, what the hell does that mean? It's not that these anomalies just caused weirdness," remarked Brannon Braga. "What's cool about them is that they're actually part of a larger conspiracy, side effects of the Spheres reengineering this area of space to be habitable for the trans-dimensional aliens."
